I started a post asking why extremely dead batteries on the RH-10 would not start charging.
I read on a post that if you attach a charged AA via the piggyback battery holder and use the unit until the AA is drained, then the AA will charge the NIMH battery enough to allow the RH-10 to recognize it and charge it fully.
In regards to these instructions....THEY WORK FLAWLESSLY!!!!!!!
Thank you soooooooooooooo much whoever suggested that!!!
